3 Claims. (01. 68-262) Wringers, as at present made, ordinarily provide a pair of wringer rolls which are subjected to yielding pressure through a spring. Means are usually provided for varying the presure of the 5 pring.

The present invention is designed to improve the pressure adjusting means by providing devices for indicating the pressure adjustment so that the operator without trial may provide the proper adjustment for the type of clothes which are being passed through the wringer. Other features and details of the invention will appear from the specification and claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing, as follows:

Fig.1 shows a side elevation of a wringer embodying the invention, the illustration being partly in section to better show construction.

m Fig. 2 shows an enlarged view of the operating screw and handle.

Fig. 3 shows a plan view of the screw and a part of the handle detached.

I marks the base of the frame, 22 theside 35 stiles of the wringer, and 3 the top bar. The top bar is secured in place at one end by the interlocking shoulders 2--a and is provided with any desirable safety release 2-D device at the opposite end of the top bar.

4 marks the lower wringer roll; 5 the upper wringer roll; 6 the drive shaft for the lower roll; I the shaft for the upper roll; 8 the bottom bearing block, one being arranged in 'each stile; -9 a support forlthe bearing block 8 arranged in the 35 stiles; Hi the upper bearing block, one being provided for each end of the shaft I, and being slidingly mounted in the side stiles.

A pressure spring ll extends across the wringer and rests on the upper bearing block. An adjust- 60 ing screw l2 extends through a nut l3 secured in the top bar. The lower end of the screw has a swivel connection II with the spring II, this swivel connection being provided with a clip l5 which is secured to the spring.

45 All of the parts so far described are or may be of standard construction.

A cross pin l6 extends through the upper portion of the screw and operates in a slot [1, in projection "a on the base I 8 of a handle IS, the

' parts II and I9 being locked together. The handle l9 has a perforation 20 through which the upper end of the screw extends. The upper portion' of the screw has the index markings 2i, 2! and 23, these markings as shown being high, med. and low.

When the screw is adjusted downwardly to adjust the spring i'or thehighest pressure, the high marking only is exposed. .As the screw is retracted to indicate the marking med." indicating a medium pressure, becomes exposed, and

as the screw is further released the index marking low is exposed, indicating the lowest operating pressure. Thus the operator is advised of the working pressure to which the wringer is adjusted without any testing with clothes or preliminary operating. concealing parts of the index leading to the index exposed more definitely 1 fixes the point of index reading and thus simplifies the structure.

What I claim as new is:

1. In a wringer, the combination of a frame; rolls mounted in the frame; means exerting yielding pressure on the rolls; a screw adjusting the means; an operating nut for the screw, the screw extending through the nut and said screw being provided with a handle, and said handle being independent of the axial movement of the screw;

. and an index indicating the degree of adjustment of the means through the action of the screw, said screw having the index scale thereon exposed through the proiection of the screw through the handle.

2. In a wringer, the combination of a frame; rolls mounted on the frame; means exerting yielding pressure on the mils; an adjusting mechanism for the means comprising a rotative and axially moving screw; and an operating handle for the screw, said handle being independent of any axial movement of the screw and the screw extending through the handle, the projection of the screw through the handle varying with the adjustment of the screw on the pressure means. 40

3. In a wringer, the combination of a'frame: rolls mounted on the frame; means exerting yielding pressure on the rolls; and an adjusting mechanism for the means comprising as members a rotative and axially moving screw and an operating handle on the screw, said handle turning with the screw and one of the members being axially stationary and an index on one of the members indicating therelation of the screw and handle and through suchrelation indicating the degree of adjustment of the means.
